Biophysics
Biophysics is a branch of physics that focuses on understanding biological phenomena by employing physical principles and tools. From the submolecular to the organismic and population levels, biophysics encompasses it all. The fields of biochemistry, molecular biology, physical chemistry, physiology, nanotechnology, bioengineering, computational biology, biomechanics, developmental biology, and systems biology all have a great deal in common with biophysical research. To "walk" along a microtubule, kinesin employs protein domain dynamics at the nanoscale.
In 1892, when Karl Pearson first coined the term "biophysics,” the field was still in its infancy. In the academic world, the study of the physical quantities (such as electric current, temperature, stress, and entropy) in biological systems is commonly referred to as biophysics. Biophysics is a broad field that includes studies of biological systems at the molecular, cellular, chemical, and biochemical levels. Biochemical and molecular biological questions are often tackled in molecular biophysics, which aims to discover the physical basis for biomolecular phenomena. Researchers in this area study the interplay between DNA, RNA, and protein biosynthesis, as well as the regulatory mechanisms that govern these processes in living organisms.
